If you're looking for a bike in Appleton, this is the place that I recommend. They sell used and new bikes, but the used bikes are often very interesting, vintage, and affordable!
Friendly people, very knowledgeable. I've gone to every local bike shop in the past, and this is the only one I have gone to since the first time I've gone there. It's a great place to buy a new or used bikes. They have tons of parts, and have a great reputation for fixing customers bikes like new. If you have a classic bike you're looking to get fixed up this is the place. Best BMX shop in the valley for sure for old, and new school. Talk to Mark. He's helped me out so much over the last few years.
